Android :: No Commons Logging In?
Jun 17, 2010
I have a pretty big library I developed specifically for use in my Android Application. However business logic itself has no dependency on Android. To preserve that, I used Commons Logging throughout this library and it's respective JUnit tests (which I run in Eclipse).
However now that I am starting to integrate it into an Activity which I launch on Android, I am unable to get my logging to work. In Eclipse/JUnit, I had simply pulled in log4j's jar file as well as a log4j.properties file. This doesn't seem to work when deploying to a device. After struggling with attempting to get that to work for several hours, I gave up and tried replacing all my commons logging stuff with android.util.Log. Now I can log on the device.. but all JUnit tests are broken. When any JUnit tries to log using android.util.Log, it throws a RuntimeException 'Stub!'.
I would prefer to revert to my commons logging approach.. if anyone can help with that.. otherwise.. what can I do to get my JUnit test cases running using 'android.util.Log'?

I'm trying to use the Amazon Web Services java sdk jar but it has references to org.apache.commons.httpclient. All I seem to have in my Android sdk is org.apache.commons.http.client, which is a different namespace and obviously causes the build to fail. I'm new to Java and Android dev... is there a way to "map" one to the other or create some sort of symbolic link? If not, does that mean I have to import a "standard" org.apache.commons library?

I want to import the org.apache.commons.net.ftp.FTP, but there is no libs for it, so I download the commons-net-2.0 lib from apache website,
I try to push this lib into /system/framework/ but I can't because the directory is a read-only filesystem, and I try to chang mode for directory, but can't work! is other methods can use the lib?

I am trying a simple send mail application using apache commons library.
Here is the code.
The email sending code is working fine in a standalone application.However when I try to run it as android application
It gave following error message. trouble processing "javax/naming/AuthenticationException.class": [2009-09-17 05:33:20 - Commons]
Attempt to include a core VM class in something other than a core library. It is likely that you have attempted to include the core library from a desktop virtual machine into an application, which will most assuredly not work. If you really intend to build a core library -- which is only appropriate as part of creating a full virtual machine binary, as opposed to compiling an application -- then use the "--core-library" option to suppress this error message. If you go ahead and use "--core-library" but are in fact building an application, then please be aware that your build will still fail at some point; you will simply be denied the pleasure of reading this helpful error message.

I'm using org.apache.commons.net.nntp to connect to a nntp server, however running a simple nntp.connect(host, port) crashes the android.
Anyone got any ideas? Do java packages work with android straight out of the box? or do they need editing?

I'm trying to write a simple web service client app for Android, and I'd like to use commons-digester to convert the service's XML responses into objects I can work with. However, I'm getting a VerifyError as soon as I try to invoke any Digester method.
I've set up my dependencies (external jars) using Maven (the Masa Android plugin for Maven, and the Maven Plugin for Eclipse). The Masa plugin seems a little bit bleeding edge, so that may somehow be the source of the problem, but I can't be sure.
How can I debug this issue further, and what, if anything, can I do to resolve it? Is it not possible to use a library as simple as Digester on the Android platform?
Here is my complete error output:

I am writing a ftp client on android sdk 1.5 with apache-commons-net- ftp-2.0. I can successfully connect to my testing ftp server but with I use listFiles() it return an empty FTPFile[].
I put the same code in a normal java program and it works fine. I don't know where is wrong. Any compatible problem when apache-commons- net-ftp-2.0 and android works together?
Here is my test code:
CODE:..................
It is actually 4 files and 1 directory in the ftp root!

I've removed my convoluted and badly malformed question so that it doesn't detract from the very neat and correct answer beneath. Given the (surprising) difficulty of finding an on-line example for doing this incredibly common task, I hope Yoni gets a few more up-ticks for his response.
So the question...How do I use Apache.Commons to upload a file to some destination. I'm using it in Android and uploading to a PHP script, but obviously it can work from any Java program and to any HTTP based listener.

In the spirit of using existing, tested and stable libraries of code, I started using the Apache-Commons-Math library and its BigFraction class to perform some rational calculations for an Android app I'm writing called RationalCalc.
It works great for every task that I have thrown at it, except for one nagging problem. When dividing certain BigFraction values, I am getting incorrect results.
If I create a BigFraction with the inverse of the divisor and multiply instead, I get the same incorrect answer but perhaps that is what the library is doing internally anyway.
Does anyone know what I am doing wrong?
The division works correctly with a BigFraction of 2.5 but not 2.51, 2.49, etc...
[UPDATE]
This was indeed a bug in the apache-commons-math 2.0 libraries. The bug is fixed in v.2.1.
It is now listed in the Fixed Issues section of the bug tracker:
When multiplying two BigFraction objects with numerators larger than will fit in an java-primitive int the result of BigFraction.ZERO is incorrectly returned..attempting to reproduce the issue and setting me on the right track.

I am trying to log into you tube using the following code
mService = new YouTubeService("Nothing", developer_key);
//Authentication try { mService.setUserCredentials(mUsername, mPassword); } catch (AuthenticationException e) { Log.v(TAG, e.toString()); }
but I am getting: ConnectYouTube: com.google.gdata.util.AuthenticationException: Error connecting with login URI. This code seems pretty basic to me and I can't figure out what mistake am I making here.

I am no good with hardware concepts. So I have this probably very silly doubt.
I want to add Log to my application. When running on an emulator, I know where to see the Log output - it's visible in the Logcat window of Eclipse.
I want to know where I can see these logs when I run it on a hardware device. I am using following command to load my app on to the device : ./adb install helloWorld.apk
So where will the log be created and under what name?

At my campus, to get internet connection, I need to log on to a SSH server like they write:.you must manually log in to the firewall server, by establishing a pseudo-tty-less ssh connection to it. The following command can be used on most systems: ssh -T -l [username] [server-URL]I must be logged on to the server for as long as I want internet.Does anyone have any idea how to accomplish this on Android?I have a little experience in writing basic apps for Android, but not much with SSH, any help is appreciated.
/Update
Tried ConnectBot, but the server replies "You may only connect without a pseudo-tty!" at login attempt. I have no idea what "pseudo-tty" is, and I have looked in the settings of ConnectBot, there is no mention of this.
/Update2
Searched for any further info about the pseudo-tty-less function, in connection with OpenSSH. No luck so far, only a definition of the -T parameter which has no equivalent in ConnectBot.

I'm running Eclipse Ganymede on Ubuntu 8.04 and suddenly with no configuration changes as of yesterday am missing logging on the Console Window. I see startup logging when I launch an app but once launched there are no more lines of information. The buttons for Verbose etc are also missing. Log.v messages are not showing. Anyone else seeing this? I'm wondering if one of Ubuntu's updates screwed things up? I may try reinstalling the plug-in or even Eclipse but thought I would check here first.

New to Android and just looked at http://developer.android.com/reference/android/util/Log.html
My question is regarding everything except debug. How do these Log entries get cleared such as Error so that they don't consume space? Also, Is there a way that the logfile can be queried so that it can be sent to a central web service or something for quality purposes etc.?

I have a widget that displays an analog clock. What I would like is for the the widget to write to a database the time when a user clicks on the widget. I've already got the databaseHelper class and have an Activity that displays a screen showing the current date and time and writes the time to a database.The AskTheTime class extends activity and logs to the database in onCreate(). But this means that it displays only the time when the widget was started - not when it was clicked. (I guess this is because I'm starting a pendingIntent) I'm not sure If I should put the database write in another method or if I should be using Intents to do this sort of thing from widgets. Any pointers would be great! I've look at several tutorials for intents but none of them seem very clear to me.
